Crowded teeth have several causes in children and adults, including genetic factors, oral habits, early loss of deciduous teeth, previous injuries or jaws, nutrition, etc. Let’s get to know those reasons in detail:

Genetic and hereditary causes

The teeth reflect the genes of the parents. If your parents had crowded teeth, you likely inherited the same thing from them.

Functional musculoskeletal oral habits

Children, teens, and adults may have oral habits that affect the balance between muscles and teeth, resulting in misaligned or misaligned teeth.

Some of these habits include:

  • Thumb sucking (thumb sucking for prolonged periods of several years).

  • Tongue thrust (thrusting the tongue forward).

  Mouth breathing.

  • Nail-biting.

Early loss of deciduous teeth

The early loss of baby teeth leaves empty spaces into which the surrounding teeth tend or lean toward. If this condition coincides with the small size of the jaw, this may lead to crowding of the teeth when the permanent teeth emerge.

jaw size

There has been a dramatic shift in the way people live and eat over the past few decades. As a result, the average jaw size has decreased, resulting in less space to accommodate the teeth. Thus, we see differences in the size of the jaw and teeth such as overlapping, crowding or spacing of teeth. In addition to the disproportionate growth in the jaws, such as the size of the lower jaw is larger than the upper jaw or vice versa, which leads to an abnormal position between the teeth. These discrepancies lead to problems with chewing, causing muscle tension in the jaws and affecting a person’s appearance as well.

Malnutrition

Health care experts point out that malnutrition in children is a growing concern, as it leads to delayed tooth formation and growth, and significantly slows jaw growth leading to severe crowding of teeth.

previous injuries

Facial injury or trauma in cases of accidents or falls may lead to the loss of some teeth, which leave empty spaces in which the remaining teeth move, resulting in crooked teeth and a change in the shape of the smile.

  aging

Our teeth undergo many changes as we age. The natural wear of the teeth over time may also contribute to misaligned teeth.

What oral and dental problems are associated with crowded teeth?

Crowded teeth cause many problems not only for oral health but also for general health.

  Difficulty chewing and digestion problems

  Uneven or misaligned teeth can disrupt normal chewing function for some people, due to misalignment of the upper jaw with the lower jaw. This difficulty in chewing puts a burden on the digestive system because food is not broken down in a way that allows the digestive acids to do their job properly.

Tooth erosion

Crowded or protruding teeth can lead to abnormal chewing patterns and malocclusions, which increases the possibility of erosion of the enamel (the protective outer layer of the teeth), which in turn causes other problems such as tooth sensitivity or tooth decay.

  Tooth decay and gum disease

Crowded teeth by themselves do not cause cavities or gum disease, but because they appear as crooked teeth, teeth that grow sideways, or simply irregular teeth, it is difficult to maintain proper oral hygiene because the toothbrush does not reach all places. . Thus, ineffective brushing leads to plaque buildup, causing tooth decay and gum disease.

the pain

Malocclusion and crowding may affect the normal functioning of the teeth. Sometimes it results in pain in the head, neck or back, as well as discomfort in the jaw joint.
